网络语音的发展提高了开发的便利性以及在不使用屏幕阅读器软件的情况下语音描述的公众可用性，扩大了其对可能受益于语音描述的用户的覆盖范围。基于现有的交互式网络媒体语音描述设计框架，我们设计了一个可选的语音功能，该功能在全球学生和教育工作者经常使用的两个PhET互动模拟中得以实现。我们对2000多名教育工作者进行了调查，以了解他们对基于网络语音的语音功能的看法和偏好，以及该功能在教学方面的广泛吸引力和有效性。我们发现教育工作者普遍认可语音功能，并且对我们提供的不同预设语音级别给出的评价比预期更为适中。我们发现教育工作者认为该功能在广泛层面以及针对特定人群都有益处，同时一些人也承认对于某些特定人群该功能仍然无效。最后，我们根据模拟体验的不同方面确定了对该功能看法的一些差异。
The evolution of Web Speech has increased the ease of development and public availability of auditory description without the use of screen reader software, broadening its exposure to users who may benefit from spoken descriptions. Building off an existing design framework for auditory description of interactive web media, we have designed an optional Voicing feature instantiated in two PhET Interactive Simulations regularly used by students and educators globally. We surveyed over 2000 educators to investigate their perceptions and preferences of the Web Speech-based Voicing feature and its broad appeal and effectiveness for teaching and learning. We find a general approval by educators of the Voicing feature and more moderate statement ratings than expected to the different preset speech levels we presented to them. We find that educators perceive the feature as beneficial both broadly and for specific populations while some acknowledge particular populations for whom it remains ineffective. Lastly, we identify some variance in the perceptions of the feature based on different aspects of the simulation experience.
